SPECIFICATION forming part of Letters Patent No. 540,838, dated June 11,1895. I l lpplication filed April 30, 1894. Serial No, 509,440. (NomodeLl .To all tcl/tom it may concern:

Be it known that I, GEORGE C. LocKLIN, of

. Kenosha, in the county of Kenosha and State of Wisconsin, haveinvented a new and useful Improvement in Fastenings for Spiral-SpringBed-Bottoms and Mechanism for Securing Such Fastenings to the Springs,of which the following is a description, reference being had to theaccompanying drawings, which are a part of this specification.

My invention has relation to improvements in fastenings for spiralspring bed bottoms, and to the mechanism for securing such fastenings tothe springs.

'The object is to provide an improved construction for preventingtilting or sidewise motion of the'bed spring, which shall combineeconomy,'simplicity, and efciency to the my improved device properlyapplied thereto.`

Fig. 2 is a detail plan view of the device, showing thelugs before beingbent over. Fig.

3 is an inverted plan'of Fig. 2. Fig. 4 is an elevation of Fig. 2. Fig.5 is a plan view of a fragment of a spring, showingthe cross-bars and myimproved device in proper adjusted position, the lugs being shown asbent over the wire. Fig. 6 is a transverse section of Fig. 5 on the line6 6. Fig. 7 is a transverse section of Fig. 5 on the line 7 7 thereof.Fig.

spring bed-bottom is placed for the proper adjustment thereto of thefastening illustrated in Figs. 2 and 3. Fig. 9 is an end View of thetable. Fig. 10 is a section through one of the adjustable bars of thetable.' Fig. 1l is a detail elevation of one of the pins of the table.Fig. 12 is a plan view of the upper end of said pin. Fig. 13 is a detailelevation of a tool for Fig. 14 is a bottom plan view of the same, andFig. 15 is a section of a fragment of the lower end of the tool. l

Like numerals of reference denote like parts throughout the severalviews.

ksides of the frame, are parallel wires 18, 18.

Each of theselwires is provided with a series of lateral V-shaped bends19. These, as will be clearly seen, extend under the upper coils of thewires. The hooked ends of short connectingwires 20, 20 connect the uppercoils of adjacent springs', said hooked ends being bent under the Vshaped bends 19, and then over the upper coils of the springs. Otherhooks 2l connect the springs to the sides of the frame 16. The baseframe (not shown) is, of course, connected up to the lower coils of thesprings in exactly the same manner as that described with reference tothe upper frame. About centrally between the upper and lower borderframes is a smaller rectangular frame 22. Connecting opposite sides ofthis frame are parallel wires 23, 23, which run through the centers ofthe springs, while connecting the two other opposite sides oftheframeare similar wires 24:, 2l, which also run through the centers ofthe springs, but beneath the wires 23.

The parts above described are common in spring bed bottoms, and henceform no part of my invention, excepting only so far as they cooperate orcombine with the other mechanism about to be described.

My improved center fastening illustrated in detail in Figs. 2, 3 and 4consists, prefer-Y ably, of a ringor annulus 25, provided on its upperside with projecting lugs 26, 26, ar ranged in sets of two. Dependingfrom the under side of the ring or `annulus are other lugs 27.

Figs. 5, 6 and 7 show more clearly thel manner in which the ring issecured within the center of a spring. It will be seen that it isarranged within the spring beneath the lower wire 2l, opposite sets ofthe lugs 26 receiving said wire therebetween, while the other oppositelugs 26 receive therebetween the upper wire 23. The next step is thebending of the ICO ` apart.

lugs, so as to securely hold the wires, and then simultaneously with thebending of the lugs the crimping of the Wires. The mechanism foraccomplishing this is clearly illustrated on Sheet 2 of the drawings,which mechanism will now be fully explained.

The numeral 2S indicates a supporting table, upon which is arrangedbetween end pieces 29, 29, a series of longitudinal beams 30. Thesebeams are provided with a series of recesses or openings 3i, which areadapted to receive thereduced or tenoned ends of pins 32. The upper endsof these pins are provided with a series of edge notches 33, whichextend a slight distance down the sides of the pin. Each longitudinalbeam is advisably provided with thirteen of these pins, arrangedequi-distances apart, and as there are nine beams in connection withthetable,this makes a total of one hundred and seventeen pins, whichnumber exactly corresponds to the number of springs employed ordinarilyin a wide bed. In narrower beds, one or more rows of springs are ofcourse dispensed with. The end pieces 2), 29 of the table are slottedlongitudinally, as indicated at 34, and as clearly shown in Fig. 9 ofthe drawings. Through these slots pass bolts 35. Each bolt enters theend of alongitudinal beam 30,aud extends across a vertical opening 36 ofthe beam, carrying on its threaded portion within the opening a nut 37.rlhe head 3S of the bolt bears against the outer side of the end piece.The opening 36 permits access to be obtained to the nut 37, whereby,when the nut is turned up tightly on the bolt, the beam is, of course,held firmly against the end piece. The object of this construction is topermit the several longitudinal beams to be adjusted closer together orfarther apart, in order to accommodate spring bed bottoms in which thesprings are arranged at varying distances In order to accomplish theadjustment, it is obvious that all that is necessary to be done issimply to loosen the nuts 37, which will, of course, permit the beams tobe moved the desired distance laterally.

Upon the upper ends of the pins 32 the fastening rings 25 are placed,the under lugs 27 thereof fitting in the notches 33 of the pins toprevent turning of the rings. The spring bed bottom is now placed uponthe table in such manner that each one of the pins 32 will extendupintoaspringabouttothe centerof said spring, the sets of lugs 26, 26,respectively, being made to embrace the wires 23 and 24 of theintermediate rectangular frame 22. The lugs 26 are bent over so as tofirmly lock the wires 23 and 24 by means of a tool 39 (Fig. 13). Thelower end of this tool is provided with intersecting V-shaped grooves 40and 41, the latter having secured therein pins 42, 42, which projectslightly below the end of the tool and are provided with grooved ends.The next step, after arranging the spring bed bottom on the table in themanner just described, is to bring the tool 39 into operation for thepurpose of bending over the lugs 26. This tool, therefore, is passedvertically through the center of a spring until the lugs 2G are receivedin the V-shaped grooves, said grooves being wide enough to admit theendsof thelugstherein. Atthesametimethe upper Wire 23 is received in thegrooved ends of the pins 42, 42. If, now, a forcible blowis given to theupper end of the tool, it is obvious that the lugs will be bent so as toclose over the Wires 23 and 24, and at the same time the pins 42, 42will bend the top Wire 23 down at the points 43, 43, (see Fig. (i) Whilethe under wire 24 by reason of the elfectof the blow on the upper wirewill be bent centrally, as indicated at 44 in Fig. 7.

It is evident that "a spring bed bottom in which the springs arestiiiened by the fasteningr devices such as herein shown and described,possesses superior advantages, the devices being of such character as tobc readily applied in the novel manner herein shown and set forth, and,when properly adjusted to the springs, preventing all sidewise ortilting motion of the springs, thereby providing a spring bed bottomwhich is practically level throughout; or, in other Words, one in whichthe springs are maintained as nearly as possible fiush with each other,and the border wires or frames standing straight at the corners.

I do not wish to be understood as confining myself to the exactconstruction of details, inasmuch as it is apparent that changes may bemade without departing from the spirit and scope of my invention. Forinstance, it is not absolutely necessary that the fastening devices 25be of circular or annular form, inasmuch as the same may be constructedeither square, rectangular, or in any other desirable shape, so long asthe sets of lugs thereof are so arranged and disposed as to rcceivetherebetween the cross Wires 23 and 24.

Having thus described my invention, what I claim, and desire to secureby Letters Patent, is-

l. The combination, of a spring bed bottom provided with a frame andwith cross wires, springs through the coils of which the cross Wirespass, said cross wires intersecting each other within the circumferenceofthe springs, a fastening device for each spring arranged intermediatethe ends of the spring, said device provided with locking meansarranged' for each cross Wire, and engaging said cross wires,respectively, at points distant from the intersection of the Wires,substantially as set forth.
